A note on We, Us and the language of email

What is it about an earnest email that tells "you" (they mean me) to do something or other? 
I do not deserve such a subordination of my decisions to the minds of others.

What ever happened to us? I mean, whatever happened  to "we?" 
I like the ring of, "We the people," and like that.

When Lincoln spoke at Gettysburg, he said, "Four score and seven years ago our fathers...," and a moment later, "We are engaged in a great civil war..,"  leading us to conclude together that, "we here highly resolve that these dead shall not have died in vain—that this nation, under God, shall have a new birth of freedom—and that government of the people, by the people, for the people, shall not perish from the earth."

I am waiting for my copy of Joe Romm's book, "Language Intelligence." I can tell from the posts of his enthusiastic reviewers that they have yet to learn to use inclusive language as well as did Lincoln.  They write that "you" should get the book. 

But should we? I might write about it after I've read the book.
